CNN article on dupe, biobricks and other low energy building alternatives

I felt I had to share this article my friend sent me. The CNN article is mainly about a new building material called 'Dupe' a brick made from sand held together by bacterial exudates fed by urine. The article also mentions, hempcrete (image 5), straw bale (image 7), cob (image 8 ), and shipping containers (image 11).

Mainstream is starting to catch up to what we have been doing in the Permaculture world. Keep up the low the low energy building designs.

I am both encouraged, hopeful, and pleasantly surprised that humankind is beginning to gain respect and understanding of the countless building methods our forebears had used for millenia in today's architectural endeavors. If these types of cooperative, grassroots, and locally sustainable building industries are better supported by the construction industry, we could see a positive shift in the "business world," as a true consciousness of societies and environment also becomes part of the "bottom line."

Thanks so much Brett for posting this...a great synopsis on ancient methods with modern applications...
